An alignment apparatus for accurately aligning a replacement spindle with a pre-existing axle shaft to facilitate repairing a damaged axle assembly. The alignment apparatus may comprise an axle clamp assembly and a spindle clamp assembly. The axle clamp assembly may be mountable to an axle shaft. The axle clamp assembly may be self-centering and self-aligning. Similarly, the spindle clamp assembly may be mountable to a spindle. The spindle clamp assembly may be self-centering and self-aligning. The axle clamp assembly may be fixable to the spindle clamp assembly. By fixing the axle clamp assembly to the spindle clamp assembly, a desired alignment between the axle shaft and the spindle may be achieved.

Assemblies and kits providing the repeatable positioning of a removable component with respect to a reference component are provided. Precision positioning members including a threaded positioning shaft associated with the reference component, a positioning sleeve associated with the removable component and an alignment nut screwed in the positioning shaft and abutting the positioning sleeve are provided. The spatial profile abutments on the positioning sleeve or positioning nut and the thread angle of the positioning shaft threads are selected to provide an automatic alignment of the positioning shaft within the positioning sleeve. A clocking angle lock for locking the relative orientation of the reference component and removable component is also provide, preferably in the shape of precision clocking members. Assemblies including three sets of precision members with slotted sleeves are also provided.

A method for positioning a body that has a surface extending along a circular arc, includes: attaching the body to a machine part that is capable of swiveling; attaching a stationary, first distance gauge; attaching a stationary, second distance gauge; determining three first distance values and three second distance values at three defined angular positions of the machine part different from each other; calculating a first offset value, based on the three first distance values and the corresponding angular positions, and a second offset value, based on the three second distance values and the corresponding angular positions; shifting the body relative to the machine part, until the first offset value is determined by the first distance gauge and the second offset value is determined by the second distance gauge within permissible tolerances.

A fastener locating tool equipped with a sensor head having one or more probes and a method for operating such a tool for precisely locating a fastener that is hidden or buried under a thick coating applied on a surface of a structure. The fastener locating tool may be manually or automatically operated. The fastener locating tool includes a platform having a central opening, means for temporarily attaching the platform to a coated surface, and a sensor head that may be easily mechanically coupled to and then later decoupled from the platform. Optionally, the fastener locating tool also includes a multi-stage positioning system with X and Y stages which may be used to adjust the position of the sensor head. The sensor head includes at least one probe which generates electrical signals indicating the presence of a fastener beneath a coating when the probe is within a detection range.
